PADLOCK.

Specification of Letters Patent.

Application filed June 1, 1909.

Serial No. 499,325.

To all whom it may concern:

Be it known that IsrDon Menronn Barman, a citizen ot the United States, and resident of the city, county, and State ot l( ew York, have invented certain new and useful Improvements in Padlocks, ot which the following is a specification.

My invention relates to a padlock adapted to a variety of uses, among which is its use on dog collars to keep the collar from being unintentionally removed, and at theI same time to provide a padlock which will be sightly and which will hang properly, tlat against the collar, which is readily manipulated to lock and unlock and which is adapted to receive a card with the owners name and address or other information showing through a display opening in the padlock, also to receive a jewel or other ornamental fixture.

In the drawings, which show one ot the itorms which my invention may take, Figure l is a rear perspective of a padlock within my invention, Fig. 2 is a vertical section partly in elevation, showing in dotted lines one of the side members when the padlock is open, Fig. 3 is a front elevation looking at the reverse side from that shown in Fig. l, Fig. It is a rear perspective view ot' the member l and related parts, and Fig. 5 is a detached perspective view ot' the bolt member.

I will now describe the preferred form of my device shown in the drawings, and will reserve it to the claims to point out the novel features and to dene the scope of the invention.

The padlock shown comprises two members l and 2 hinged together at 8. The member l is a hollow member with a bottom a, sides b and atop portion c. Said portion c consists of extensions from the opposite sides Z) folded over and more or less joining in central position over the top of the member. For convenience in getting at the interior mechanism contained in the member l, said top portion c does not completely cover over its top. The other member 2 is in the nature of a plate having a display opening It through it, and acting as a hinged lid complet-ely covering the top ot the member l. Furthermore, this member 2 'has a hook 5 springing integrally from it toward the first member and arching down over an end of said member in close proximity therewith when the two members are together. The extremity ot the hook 5 is received in a slot in the end 7) of the member l and has side lugs 1G which are then received under the end to prevent the extremity of the hook from being' pulled endwise away from the slot.

is the bolt member ot' the padlock shown in perspective in Fig. 5 and located in the interior of the member l to slide therein with its bolt projection or tongue /Z directed tovard the extremity of the hook 5, as shown in Fig. 2. This member (i is seen to consistconveniently of a single piece ot sheet metal, shown in Fig. 5, and comprises a body portion c sliding against the bottom a ot the member l, side wings f sliding against sides L of the member l, and another side wing g located opposite the tongue d. rlhe body portion e has an opening /t through it to receive the bit T ot the key S. The keyhole t) is termed in the bottom a ot the member l, and there is a circular opening l0, Fig. it, (compare Fig. 2) in the top portion f; ot 'the same member l to receive the point ll of the key.

The bolt member (3 is spring-held so that its tongue (Z is normally in locking position relative to the extremity otl the hook 5 by a coil spring l2 surrounding the hinge pin 3 between the members l and Q, which spring has one extremity 13 working against the bottom a of the member l, and its other extremity 14 working againstI the plate 2, thereby tending normally to torce the two members l and 2 of the padlock into open position. The extremity let is further continued to bear in yielding manner against the wing g of t-he bolt member 6, whereby said member is given normal tendency in a direction toward the hook 5 to interlock its tongue (Z with said hook, as shown in Fig. For this purpose, the tongue Z is bent inwardly relative to the body portion c of the member G (see Figs. 2 and to receive the extremity of the hook 5 between it and the bottom a of the member l, as best shown in Fig. 2.

The extremities ot the hook 5 and ot the tongue Z are beveled so that in pressing the. members l and 2 together' from their open position, as indicated by the dotted lines in Fig. 2, the tongue Z will ride under the extremity of the hook 5, then will spring up in back of said hook under the action of spring l2 after the members l and 2 are completely together.

The unlocking ot the members is effected llO by the key 8 which upon being inserted through the keyhole and turned to carry its bit 7 into contact with the wing g of the bolt member 6, said member is forced in contrary direction to the tendency of the spring' 12, and its tongue d is carried below the extremity of the hook 5 so that the members 1 and 2 can be separated and, in fact, will separate of their own accord, due to the heretofore described action of the spring 12.

It will be noted from an inspection of Fig. 2 that a card 15 can conveniently be inserted in back of the display opening l in the member 2 and between said member and the top portion c of the member 1, which latter forms a desirable backing for the card. Of course, on this card any desired information may be written, such as the owners name and address. Moreover, the card is readily insertible and as easily removed. Instead of a card, an ornamental jewel may be substituted projecting out through the opening 4, which opening' for either purpose may be of various shapes.

The padlock is exceedingly simple to manufacture and, in fact, comprises only three main parts, to wit, the members 1 and 2 and the bolt member 6. 1t is, therefore, readily assembled.

Another feature of prime advantage consists in the fact that thc nature and relation of the hook 5 to the body portion of the padlock permits it to lie flat against the collar and not only thereby give a sightly appearance but also to present at all times the display opening of the padlock in proper position for viewing.

Having thus described my invention, what I claim is 1. A padlock comprising in combination two hinge-connected members; a hook springing integralljT from one member toward the other and arching down in close proximity to said other member when the members are together, thereby closing the open side of the hook; a locking member t adapted releasably to engage the end of the hook of the hook-provided member, and being movably mounted on the opposite member.

A padlock comprising in combination two members hinged together, the lirst being a hollow member with a bottom and sides, thc second being a plate hinged to the lirst member to form a lid to its top; releasable locking means adapted to lock said members together; and a hook springing integrally from the second member toward the iirst and arching down over an end of the first member in close proximity therewith when the members are together.

3. A padlock comprising in combination two members hinged together, the first being a hollow member with a bottom and sides, and also having a top portion extending across between its sides, the' second member being a plate with a display opening through it, said plate being hinged to the first member to form a lid over its top releasable locking means adapted to lock said members togethe and located in the interior of the first member; and suspension means on one of the members.

4. A padlock comprising in combination two hinge-connected members which inclose a space when the members are together; a hook springing integrally -from one member and arching down in close proximity with t-he other member when they are together, thereby closing the open side of the hook; a bolt slidable in said space to and away from the hook into respectively a locking and an unlocking position, said bolt being mounted on the opposite member from that having the hook, and when in its locking` position projecting beyond the free end of said hook adjacent its inner side.

5. A padlock comprising in combination two hinge-connected members which inclose a space when the members are together;` a hook springing integrally from one member and arching down in close proximity with the other when the members are together, thereby closing the open side of the hook; a key-actuated bolt slidable in said space to and away from the hook into respectively a locking and an unlocking position, said bolt being mounted on the opposite member from that having the hook, and when in its locking position projecting beyond the free end of said hook adjacent its inner side, and being' key-actuated out of said locking position; and a spring acting upon the hinge-connected members tending to open them, and further acting on the bolt tending to move and retain it in its locking position.

6. A padlock comprising in combination two hinge-connected members, one of said members having a slotted side; a hook springing integrally from the other member and arching down to have its free end received into the slot in the side of the other member when said members are together, said free end of the hook having a projection which underlies said slotted side; and releasable locking means adapted to lock the hinge-connected members together.
